Example 1 with ListQueries

use of org.apache.rya.streams.api.interactor.ListQueries in project incubator-rya by apache.

the class ListQueriesCommand method execute.

@Override

    requireNonNull(args);
    // Parse the command line arguments.
    final KafkaParameters params = new KafkaParameters();

    }
    // Create the Kafka backed QueryChangeLog.
    final String bootstrapServers = params.kafkaIP + ":" + params.kafkaPort;
    final String topic = KafkaTopics.queryChangeLogTopic(params.ryaInstance);
    final QueryChangeLog queryChangeLog = KafkaQueryChangeLogFactory.make(bootstrapServers, topic);
    // The ListQueries command doesn't use the scheduled service feature.
    final Scheduler scheduler = Scheduler.newFixedRateSchedule(0L, 5, TimeUnit.SECONDS);
    final QueryRepository queryRepo = new InMemoryQueryRepository(queryChangeLog, scheduler);
    // Execute the list queries command.
    try {
        final ListQueries listQueries = new DefaultListQueries(queryRepo);
        try {
